APPLICATION NOTE 125
Using Dallas Battery Management ICs with High Voltage Battery
Packs

Abstract: This application note presents to the reader a reference circuit design that allows the use of the Dallas
Semiconductor DS2438 battery monitor in a high voltage battery pack. Originally designed for use in battery
packs whose voltage is less than 10 volts, this note explains the required circuitry needed to enable the
DS2438 to monitor packs of higher voltage while maintaining accurate battery current and voltage
measurements. The selection criteria for each component in the reference circuit are explained in detail
